Change Order No.1 provides for the following:
•Changing a 12-inch oil cushioned check valve to 12-inch Surge Buster check valve to allow the valve to be
removed from the vault without the need to disassemble the lever arm.
•Connecting the 24-inch pump suction piping to the existing 36-inch line by wet tap instead of cutting in a
tee. The 36-inch pipe is B-303 instead of C-303 as shown in the plans and cannot be cut and welded. A
wet tap is the preferred connection alternative to minimize disruption of water supply to the Tarleton
campus,
•A credit for generator factory witness testing which is not required for this size generator.
It is understood and agreed that the acceptance of this Change Order by the contractor constitutes an accord and satisfaction and represents
payment in full(both time and money)for all costs arising out of,or incidental to,the above Change Order.

❑ INFORMATION, ❑ INTERPRETATION, ® PROPOSED CHANGE
Description—36"x 24"Tie-In
Problem—Plan Sh.C-6 calls for a 36"x 24"tee installed using a buttstrap into the existing line. Per the
attached Thompson Pipe Drawings Project 170061,the existing 36"pipe is B303 w/a 10-gauge steel cylinder.
Per Jifco the 10-guage steel cylinder is not thick enough to properly weld a buttstrap.
Solution—Revise the 36"x 24"tee to a saddle and wet tap application.
